Why is terrestrial radiation weaker than solar radiation? different color -lower temperature - longer wavelength -higher temperature -shorter wavelength

-longer wavelength

Terrestrial radiations are radiations that are emitted by earth and the atmosphere. These radiations are emitted by naturally occurring radioactive materials, like uranium, thorium and radon. These radiations lies in the infrared region of the electromagnetic spectrum. The solar radiation lies in the visible region of the electromagnetic spectrum. These are short wavelength rays. The short wavelength rays have more penetrating power against the substrate than longer wavelength rays. The shorter wavelength makes the solar radiation more penetrative and powerful than long wavelength terrestrial radiations.

Hence, longer wavelength makes the terrestrial radiation weaker than the solar radiation.
